MANHASSET - A new traffic system designed to keep emergency service workers and motorists safe was unveiled at certain traffic stops in Nassau County Saturday.

The system was created after a study revealed that crashes involving emergency vehicles are the second highest cause of death among firefighters in the United States.  

Officials say the new system uses GPS technology and turns traffic lights green in the direction emergency vehicles are traveling. Lights in all other directions are turned red.

The new system was funded through a $125,000 grant secured by Assemblywoman Michelle Schimel (D-Great Neck).  She says she hopes the technology will soon be used in communities throughout the rest of the county.

So far, the system has been installed in all of the Manhasset Lakeville fire trucks and ambulances, as well as eight intersections along Northern Boulevard from Shelter Rock Road to Middle Neck Road.
